South Florida Rainy Season Could Wind Up On Drier Side
May 20, 2015 Despite an earlier-than-normal start to South Florida’s rainy season, the outlook for this wet season is for near- to slightly below normal rainfall across the area, according to the National Weather Service (NWS).
May and June will likely have above-normal rainfall, with a possible drier-than-normal period commencing sometime in July and continue through much of the remainder of the wet season.
One of the primary factors to this rainy season is the presence of El Niño through the summer and fall. El Niño influences large-scale weather patterns, which affect summer rainfall across South Florida. During many El Niño summers, South Florida sits on the northern edge of the climatologically favored Caribbean dry summer regime, with some years extending more into Florida and other years remaining south of the state. The most likely range for this wet season’s rainfall compared to normal is from 75% to 95% of normal, with a few areas likely to see higher or lower ratios.
El Niño also is impacting initial outlooks for the 2015 Atlantic hurricane season.
The NWS also is issuing a heads up that this wet season’s outlook of wetter-than-normal conditions in late May and June could mean a more active severe weather period, including the threat of damaging thunderstorm winds, hail, flooding, and tornadoes.
The temperature outlook for the wet season is for the likelihood of above normal temperatures, generally within 1°F to 2°F above normal.
